摘要： The electric vehicle according to the present disclosure is configured to be able to select a traveling mode between an MT mode in which an electric motor is controlled with torque characteristics like an MT vehicle having a manual transmission and an internal combustion engine, and an EV mode in which the electric motor is controlled with normal torque characteristics. The controller of the electric vehicle controls the electric motor in the MT mode such that responsiveness of the motor torque with respect to a change in the operation amount of the accelerator pedal is lower than in the EV mode.

摘要： A method for learning engine clutch kiss point of a hybrid vehicle is provided. The method includes adjusting a speed of a driving motor to be reduced when a deceleration event is generated in front of the hybrid vehicle and adjusting a speed of an engine to be synchronized with the speed of the driving motor. An engine clutch that connects the engine with the driving motor or disconnects the engine from the driving motor is engaged to start and then a kiss point of the engine clutch is learned by detecting the kiss point that is generated when the engine clutch is in a slip state.

摘要： A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a trailer, a tractor-trailer configuration, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

摘要： A powertrain assembly has multiple torque actuators. The assembly includes a first controller configured to control a first torque actuator and a second controller configured to control a second torque actuator. The first controller is configured to receive a signal from an input sensor and convert the signal into a torque demand. The second controller is configured to receive the torque demand from the first controller and determine respective optimal torque allocations for the first and second torque actuators based on the torque demand and a plurality of optimization factors. The first controller includes a processor and tangible, non-transitory memory on which is recorded instructions for executing a method of controlling the multiple torque actuators across the at least two controllers via a dynamic look-up table. The dynamic look-up table is populated by a plurality of stored torque production allocation values based on a respective plurality of torque requests.
